Ruby on rails 轨道&x2B；Strongbox:TypeError:can'；t强制转换Strongbox:：锁定到二进制

当我尝试在console中创建新录制时，出现以下错误：

TypeError: can't cast Strongbox::Lock to binary

但是，我使用Strongbox的其他表工作正常。 我的模式如下所示：

create_table "recordings", force: true do |t|
t.datetime "date"
t.string   "position"
t.datetime "created_at"
t.datetime "updated_at"
t.integer  "patient_id"
t.binary   "sound_file"
t.binary   "sound_file_key"
t.binary   "sound_file_iv"
t.binary   "image_file"
t.binary   "image_file_key"
t.binary   "image_file_iv"
t.binary   "audio_data_points"
t.binary   "audio_data_points_key"
t.binary   "audio_data_points_iv"
end

create_table "notes", force: true do |t|
t.integer "user_id"
t.integer "recording_id"
t.integer "patient_id"
t.binary  "content"
t.binary  "content_key"
t.binary  "content_iv"
end

class Note < ActiveRecord::Base

  validates :content, presence: true

  belongs_to :user
  belongs_to :recording
  belongs_to :patient
  encrypt_with_public_key :content,
    :key_pair => Rails.root.join('config','keypair.pem')
end

class Recording < ActiveRecord::Base

  validates :date       , presence: true
  validates :position   , presence: true
  validates :sound_file , presence: true , uniqueness: true
  validates :image_file , presence: true , uniqueness: true

  has_many :notes, dependent: :destroy
  has_many :srecordings
  has_many :users, through: :srecordings
  belongs_to :patient

  encrypt_with_public_key :sound_file, :image_file, :audio_data_points,
    :key_pair => Rails.root.join('config','keypair.pem')
  end

我的模型是这样的：

create_table "recordings", force: true do |t|
t.datetime "date"
t.string   "position"
t.datetime "created_at"
t.datetime "updated_at"
t.integer  "patient_id"
t.binary   "sound_file"
t.binary   "sound_file_key"
t.binary   "sound_file_iv"
t.binary   "image_file"
t.binary   "image_file_key"
t.binary   "image_file_iv"
t.binary   "audio_data_points"
t.binary   "audio_data_points_key"
t.binary   "audio_data_points_iv"
end

create_table "notes", force: true do |t|
t.integer "user_id"
t.integer "recording_id"
t.integer "patient_id"
t.binary  "content"
t.binary  "content_key"
t.binary  "content_iv"
end

class Note < ActiveRecord::Base

  validates :content, presence: true

  belongs_to :user
  belongs_to :recording
  belongs_to :patient
  encrypt_with_public_key :content,
    :key_pair => Rails.root.join('config','keypair.pem')
end

class Recording < ActiveRecord::Base

  validates :date       , presence: true
  validates :position   , presence: true
  validates :sound_file , presence: true , uniqueness: true
  validates :image_file , presence: true , uniqueness: true

  has_many :notes, dependent: :destroy
  has_many :srecordings
  has_many :users, through: :srecordings
  belongs_to :patient

  encrypt_with_public_key :sound_file, :image_file, :audio_data_points,
    :key_pair => Rails.root.join('config','keypair.pem')
  end

class注释Rails.root.join（'config'，'keypair.pem'））
结束
类录制Rails.root.join（'config'，'keypair.pem'））
结束

我以前从未使用过保险箱，但它在其他任何地方都能正常工作，所以我不太明白这一点。想法？

唯一性验证与strongbox不兼容。您的录音模型是唯一检查声音文件和图像文件唯一性的模型。对您来说，最好的方法是在此处添加自定义验证以检查唯一性。令人惊讶的是，我用完全相同的模型得出了这个结论：）

另外，为了唯一性，我正在自己实施自定义验证
